Answer:

x = 11

Step-by-step explanation:

5х – 12 = 3х + 10

Subtract 3x from both sides, since x can only be on one side

5х – 12 = 3х + 10

- 3x - 3x

------------------------

2x – 12 = 10

Add 12 to both sides, because the 12 is negative and we need the x to be alone

2x – 12 = 10

+ 12 + 12

------------------------

2x = 22

Divide both sides by 2, so we get x all by itself

2x = 22

x = 11

Find the difference (5a^2+4ab-3b^2)-(-5ab+4b^2+3a^2)

Vesna [10]

Answer:

$\boxed{\bold{2a^2+9ab-7b^2}}$

Step By Step Explanation:

Remove Parenthesis: (a) = a

$\bold{5a^2+4ab-3b^2-\left(-5ab+4b^2+3a^2\right)}$

Simplify $\bold{-\left(-5ab+4b^2+3a^2\right)}$

$\bold{5ab-4b^2-3a^2}$

Rewrite Equation:

$\bold{5a^2+4ab-3b^2+5ab-4b^2-3a^2}$

Simplify $\bold{5a^2+4ab-3b^2+5ab-4b^2-3a^2}$

$\bold{2a^2+9ab-7b^2}$

Jaiden ran a 100 yard dash three times and took the average of his times. His times were 12.7, 11.2 and 11.8 seconds. On average

tekilochka [14]

Using the mean concept, it is found that on average, it takes him 11.9 seconds to run a 100 yard dash.

The mean of a data-set is given by the <u>sum of all observations in the data-set divided by the number of observations</u>.

In this problem, the three observations are given by:

12.7 s, 11.2 s, 11.8 s.

Hence the mean is:

M = (12.7 + 11.2 + 11.8)/3 = 11.9.

On average, it takes him 11.9 seconds to run a 100 yard dash.
